The topic is one misconception people seem to have, in addition to the thought that speed is everything in lure-coursing. The dog may be fast in the backyard or in the ‘training’ where the pulls are 250m. But the real challenge of the 600-1000m lure coursing trial is something completely different.
How to tell the difference? In the backyard (or normal walkie), use a watch to time the actual time your dogs are running at a time. Constantly running, that is, at their full -or playfull- speed before giving in to trot. You might be surprised how little they really run, especially if you compare that to the time the dogs run in a lure-coursing trial.
How long is a trial, then? Depending on the track, at the average speed of 40km/h the normal track from 600-1000 m lasts anything from 1 minute to 1.5 minutes. On average the run craze of a dog at the back yard takes about 10-15 seconds and after that the dog is ready to go in. It may run like a lunatic, fast as lightning and all, but the real challenge is avoided.
The lactic acid threshold.
At about 100 meter point, which is about 6 seconds from the start, the dog has used the immediate energy reserves in the system and the lactic acid starts to mount into the muscles. This causes ache, stiffness and discomfort, and the dog will cease running if the reason to run is not strong enough. At the backyard the reason may be to release some tension and it’s over in the 10 seconds. In the trial it is the instinct to chase the lure, and it may not be enough to keep the dog interested after coming tired and stiff.
Each and every dog is the best in the world to it’s owner, that’s for sure. But the dog running at backyard/training/walkies is not necessarily the fastest or best in the lure-coursing trial, if it hasn’t gotten used to straining herself beyond the threshold.
Even then there may be something which causes her to quit before the trial is over. But that’s another story alltogether.
